TLD has performed a teardown of the iPhone 5 and attempted to install its internal components into the leaked gold iPhone 5S housing.

Of course, the iPhone 5S screw holes didn't line up with the logic board from the iPhone 5. Also the SIM card tray position didn't line up with the opening on the iPhone 5S.

It appears as though the logic board will be moved slightly to the right indicating that while the iPhone 5S will have a more powerful processor it will come in a slimmed down form factor. Notably, this leaves more room for the battery on the left.
